After all, the number of monsters outside the valley is not too large, and most of them are iron backed wolves and flying red tigers. Although the shadow blood cat occasionally sneaked attacks and injured two students, it still failed to prevent Li Mu from rushing into the valley.

"Sir, someone has come to meet us!"

In the valley, a soldier with a heavy anti-aircraft machine gun shouted excitedly, but at this time, a fishy wind appeared.

A strange bird the size of a foot smashed the soldier's head with a fierce claw. Its sickle claws deeply penetrated the soldier's body and wanted to fly away with a flap of its wings.

"Beast!"

With a flash of cold light in Li Mu's eyes, he roared and jumped fiercely, and directly punched the strange bird. The strange bird was suddenly blasted out of a blood hole. It fell to the ground with a cry and struggled for a few times.

"Colonel, how many people do you have?" Li Changhe glanced at the position and asked the soldier with the highest rank who was covered in blood.

"We still have 36 people. The others are dead. Leave us alone. The materials we transport must be sent to Chengdu!" Cried the colonel.

There were hundreds of soldiers in the transport plane, but most of the soldiers had died in the crash and the previous battle.

"Headmaster, kill it first. We don't have time to delay here!" Li Mu shouted to Li Changhe while firing with heavy anti-aircraft machine guns.

If Li Mu's inference is correct, I'm afraid the monster of demon mountain will come soon. It's too late to want to leave at that time.

The heavy anti-aircraft machine gun spewed out fire snakes, and numerous armor piercing bullets swept away at the monsters, but now the power of gunpowder weapons has decreased by two-thirds. The monsters are steel muscles and iron bones, and they also have evil Qi and body protection.

Even a heavy anti-aircraft machine gun needs 10 or 20 bullets to kill an iron backed wolf, but those monsters are very flexible. In addition, there are few heavy anti-aircraft machine guns, so the effect of killing monsters is very poor.

"Where are the materials you transport? Take all the supplies and we'll kill out! " Li Changhe nodded and said immediately.

"Here!" The Colonel stumbled into the wreckage of the transport plane and took out a heavy metal box from the transport plane.

The box is about the size of a small cabinet and looks very heavy. A box weighs at least hundreds of kilograms, but this weight is not a big problem for a martial friar.

"Here, ten boxes in all!"

"Is it Lingjing? The provincial capital sent such Lingjing! "

As soon as those boxes were moved out, Li Mu immediately noticed that there was plenty of aura in them. The abundance of aura in this kind of aura crystal could not be compared with that of Xingguang crystal, but after all, Lingjing was Lingjing, which was the top ten boxes.

If all the Lingjing energy is absorbed by the Star Destroyer, I'm afraid the Star Destroyer's energy will be greatly improved immediately, and even start self-healing.

"However, what does Chengdu fortress need so many Lingjing to do?" A look of doubt appeared on Li Mu's face.

In the memory of those 30 years, Chengdu fortress should have lost all Lingjing, so there was no news about these Lingjing in Li Mu's memory.

Chengdu fortress asked for so many Lingjing to come here for no reason.

"Li Mu, you arrange people to take the box. People can die, but the box can't be lost!" Li Changhe said in a deep voice.

"Elder martial brother, you choose people!" Li Mu nodded solemnly and said directly to Li Luohan. Then he directly lifted a box and carried it on his back.

On the other side, Li Luohan picked up a box and arranged for eight other students from Wudao university to carry it.

"Come with me, fight out, everyone protect the man carrying the box!"

Li Changhe glanced at Xu rushong, and Xu rushong nodded. Li Changhe motioned the soldiers to keep up, and then rushed out directly.

With the help of master banbu and the help of teachers and elite students at the level of heaven and earth, the iron backed wolf and flying red tiger couldn't stop Li Mu at all, but these monsters, which are usually very cunning and will give up the attack when there is something wrong, rushed to the team bravely and fearlessly.

"They are really commanded by powerful monsters. These monsters just want to hold us down and don't fight with them!" Li Mu said in a deep voice.

"Li Mu is right. Don't entangle with them and rush out directly!"

Xu rushong said immediately.

Once he began to break through, friar Wu's advantages were immediately brought into play, but friar Tao's speed was not as fast as friar Wu. Students of Wudao university had to take into account students of the monastic college. Li Changhe had to slow down several times when he wanted to speed up.

As a last resort, Li Changhe could not make the decision to abandon these monastic students.

Even if the speed slowed down a lot, soon the demons outside the valley were killed. These demons were killed and soon began to wander around the team to attack. Their purpose was to slow down Li Mu and them.

"Listen, it's the sound of a helicopter!"

At this time, someone in the team suddenly shouted excitedly. Li Mu listened. Sure enough, he heard bursts of propeller sound.

There are no fighters in Chengdu fortress, and the temporary runway in the fortress can't let fighters take off and land. Only an 22, a transport plane that can take off and land at the airstrip, can take off and land on the temporary runway of Chengdu fortress.

At present, there are only a dozen armed helicopters and two or three transport helicopters left in Chengdu fortress, which is also all the air force of Chengdu fortress.

"Coming, it's an armed helicopter. They're coming!"

Soon there were many black spots in the sky. More than a dozen armed helicopters escorted two transport helicopters quickly came here, and UAVs in mid air were showing them the way.

This time, Xia Lao's armed helicopters have poured out. I'm afraid these armed helicopters are dispatched with the determination to die.

"No!"

But at this time, Li Mu suddenly changed his face, jumped directly into a big tree and looked back at the demon mountain.

The monster mountain ran towards ten thousand animals, and the ground trembled, like an earthquake. In the sky, at least hundreds of thousands of bird demons rushed here.

"It's a group of monsters!"

Everyone's face suddenly turned pale. The speed of the monster was much faster than that of Li Mu. At the present speed, it won't take long for those monsters to catch up with them, and the speed of the bird demon was faster than that of the ordinary monster.

"Whoosh, whoosh!"

Armed helicopters did not wait for those bird demons to approach and directly began to launch missile attacks. Each of these armed helicopters could carry eight missiles. More than a dozen armed helicopters opened fire at the same time, and the dense missiles in the sky blasted at those bird demons.
